Résumé
Experimental characterization of beams deflections of Douglas fir (Pseudotsuga Menziesii) and White fir (Abies Alba Mil) are investigated herein, especially the impacts of the relationship of Relative Humidity (RH) and Temperature (T) on their behavior. The creep tests are performed in an uncontrolled environment where the evolutions of climatic parameters (RH and T) and data of the deflection are continually recorded. The results show that, the deflection increases after a delayed time during the drying process and heating phases.
